Well, I guess I can integrate the derivatives and get this answer, but I have to solve it with methods of mean value theorem and gradients... How should I proceed? Thank you.

Start by looking at the function . Apply the mean value theorem to show that . Then, knowing that , fix x and apply the mean value theorem to the function to show that .
